In the follow up to last year’s Monster Mako, marine biologist Greg Stuntz returns to the Gulf of Mexico along with professional shark tagger Keith Poe, and fellow marine biologist Matt Ajemain. The team sets out to document a live predation of a “grander”; an enormous Mako shark that reaches 10 feet and 1,000 pounds. Granders become more secretive and hunt larger prey, making them harder to find – until now.
